Regarding the ZEOvit System - "The purpose of the system is to create a low nutrient, near natural levels, environment. The goal is to reduce measurable levels of nitrate (NO3) and phosphate (PO4) without lowering the levels of important minerals, like calcium (Ca), magnesium (Mg), Potoassium (K+) and carbonate hardness (KH), such that addition of these trace elements is minimal."
